Bastl SPA

SPA opens up a whole new level of functionality for Bastl's GrandPa grandular sampler module. It implements CV inputs for all crucial parameters and provides a dedicated clock input for influencing grain shifts. Every input features a dedicated attenuator and requires positive CV for proper functioning.

SPA Features

  • Independent CV inputs for most parameters of the grandPa module
  • CV inputs with attenuators are normalised to 5V so the attenuators work as direct controls of the parameters for both channels A and B of the grandPa
  • CV inputs react only to positive voltages from 0-12V
  • Grain Size and Shift Speed CV inputs with attenuators
  • Switch to select whether the other two CV inputs with attenuators control Start / End  or Attack / Release parameters
  • Crush cv input
  • Grain Sync input to trigger grain shift
  • Eurorack Module
  • Width: 5HP
  • Depth: 50mm
  • Current Draw: pulls power from GrandPa
